Dr. Y. S. Parmar University of Horticulture & Forestry, Solan

Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Solan, was established on 1st December, 1985 with the objective to promote education, research and extension education in the fields of Horticulture, Forestry and allied disciplines. Late Dr. Yashwant Singh Parmar, the first Chief Minister and the architect of Himachal Pradesh perceived the importance of Horticulture and Forestry to develop and improve the State economy which led to the establishment of this University. Its history lies in erstwhile Himachal Agricultural College, Solan, established in 1962 and affiliated to the Panjab University. It became one of the campuses of Agriculture Complex of Himachal Pradesh University on its formation in 1970. Consequent upon the establishment of Himachal Pradesh Krishi Vishvavidyalaya in 1978, this campus became its Horticulture Complex and finally in 1985, assumed the status of a State University, being the only University in the country engaged exclusively in teaching, research and extension in Horticulture and Forestry. The University is located at Nauni in Solan District of Himachal Pradesh, 13 km from Solan on Solan-Rajgarh Road, at an elevation of 1300 metres above mean sea level. Solan town is situated on national highway (NH-22) and is well connected by train and bus services. The University has four constituent colleges, out of which, two are located at the main campus Nauni, one for horticulture and the other for forestry, having 9 and 7 departments, respectively. The third College i.e., College of Horticulture & Forestry is located at Neri in Hamirpur District on Nadaun-Hamirpur state highway, about 6 Km from Hamirpur town and is well connected with bus service. The college offers three Undergraduate Degree Programmes i.e. BSc (Hons.) Horticulture, BSc (Hons.) Forestry and B. Tech. Biotechnology and MSc degree programme in a few subjects. The fourth college i.e. College of Horticulture and Forestry, Thunag (Mandi) is located at Thunag District Mandi. This college offer BSc (Hons.) Horticulture and BSc (Hons.) Forestry degree programme. In addition, there are five Regional Research Stations, 12 Satellite Stations and five Krishi Vigyan Kendras (KVKs) situated in different zones of the State.

    Exploitation of aphelinid endoparasitoids, Encarsia sp. and Eretmocerus sp. and entomopathogenic fungi for the suppression of greenhouse whitefly
    (2010) REECHA; CHAUHAN, USHA
    ABSTRACT The present study entitled “Exploitation of aphelinid endoparasitoids, Encarsia sp. and Eretmocerus sp. and entomopathogenic fungi for the suppression of greenhouse whitefly” was carried out during 2008 and 2009 at Nauni, Solan, H.P. Two endoparasitoids viz. Encarsia sophia (Griault and Dadd) and Encarsia inaron (Walker) and one ecto-endoparasitoid, Eretmocerus delhiensis Mani. were identified and found parasitising the greenhouse whitefly infesting different ornamental plants (fuchsia, rose, sunflower, chrysanthemum, petunia and alstromeria), vegetable crops (tomato, cucumber, egg plant, French bean and pumpkin), strawberry, ashwagandha and milkweed. The mean parasitisation of E. sophia was maximum (3.02%) followed by Er. delhiensis (1.27%) and E. inaron (0.74%) from May to September on all the vegetable crops. The developmental biology of E. sophia was minimum on whitefly infesting fuchsia (13.73 days) and maximum on tomato (19.53 days) plants while that of E. inaron was minimum on tomato (17.90 days) and maximum on French bean (19.00 days). In Er. delhiensis, the duration of the development period was minimum on French bean (13.68 days) and maximum on fuchsia (15.30 days). The true intrinsic rate of increase (rm) of E. sophia was found to be higher on whitefly infesting fuchsia (0.183) than on French bean (0.171). This value for E. inaron on tomato was 0.111 while for Er. delhiensis on French bean it was 0.157. On comparing the efficacy of fungus under laboratory conditions, Verticillium lecanii gave maximum mortality (60.00 %) at 109 spore/ml on 15th day, whereas comparatively low mortality (31.25%) was observed with Paecilomyces fumosoroseus. The combination of V. lecanii with E. sophia was found to be effective and gave maximum mortality (78.33%) on 15th day when E. sophia was released after 3rd day of V. lecanii application.
